Hollywood invaded Washington D.C. this weekend to celebrate President Barack Obama’s Second Inauguration, and four years after the first, hope and change was still on everyone’s minds.

“omg! Insider” caught up with all of the celebrities at this weekend’s Inaugural festivities – including the Creative Coalition Dinner, the Kids’ Inaugural Concert, and the Newsweek/Daily Beast Brunch -- where we asked them how they’d hashtag their thoughts and experiences over the weekend.
